55 were connected to the strand at all times. a stop-motion member orlever is movably 55 mounted on a standard and normally positioned orbiased away from stopping position. A strandsupporting bobbin isrotatably mounted on the standard, upon which is also mounted amechanism or means including a structure that is biased, as by a spring,toward position to actuate the stop-motion lever to stop the machine.'Ihis mechanism is also operative, as by a brake or clutch, for holdingand releasing relation to the bobbin for movement therewith, andrelative thereto, responsive to variations in tension on the strand andoperates in accordance with other new features, such as acting as a lockto hold certain parts of the bobbin together.

Referring to Figs. 1 to 9, inclusive, the structure thereof comprises abase or support l5 in-4 cluding a pin i6, for engaging a drive gear,carrier-foot plates I1 having a heart piece I9 therebetween forcooperation with usual intersecting annular sinusoidal raceways of abraiding machine, a double-arm standard 22 having arms 23 and 24 and atop portion 26 for supporting a yarn-guide eyelet 21 and rendering thestandard of inverted substantially U-shape on the carrier foot, andupstanding projections 29 for supporting a pin 39.

A lever 32, pivoted of substantially strap-loop shape having a midand anarrow end 35 mounted on the pin 38 between the projections 29. Ahelical spring 31, Fig. 9, about the pin 30, has one end 38 biasedupwardly against the lever 32 and the other end 39 biased downwardlyagainst the top carrierfoot plate l1, thus biasing the lever clockwise,or upwardly, as viewed in Figs. 2, 7 and 8.

A boss 42 on the standard arm 24 has a small bore 43 and forked portions44 inside the arm providing slots 45. A boss 41, on the arm 23, has alarge bore 48 and outer end slots 49. An axle 59, having a large bodyshank section 5l Yfor the bore 48 and extending nearly to the boss 42,and a small leading-end shank section 53 for the small bore 43 of theboss 42, also has a rounded end 54 on its small shank section tofacilitate its insertion into the standard arms, and to constitute areverse push button for removing the axle, and carries a transverse pin56 for position in the slots 49.

Asseen in Figs. 2 and 3, a latch member 58, constructed of strap metal,is bent on its flat sides to be of substantially U-shape, Fig. 3,thereby providing one arm 59 acting as a stop against the boss 41 and anarm 60 for movement between positions over and aside the adjacent end ofthe axle 58 about a pivot pin 62 on the standard arm wise, as viewed inFig. 2, to a position in which the axle is held in place.

A bobbin structure 64.comprises an outer spool portion including anaxial cylindrical wall 65, on a strand 66 is wound, iianges Gland 68,projecting radially inwardly from the wall 65, and spool and flanges 69and 10 projecting radially outwardly from the vcylinder 65, The larlge68 is journalled on a flange 12 of a bobbin core member or sleeve 13having clutch projections 14 for position in the slots 45, between theforks of the portion 44 on the -standard arm 24, to prevent turning ofthe sleeve 13.

Another bobbin core member or sleeve 15 has a flange 16 fitting the ange61 for journal movement relative thereto and movement therewith,depending upon whether the bobbin and the sleeve are released orconnected by a brake device, as will appear. 'I'he sleeve 15 has aportion telescoped into the sleeve 13 and held axially thereto, butpermitted rotation relative thereto, as by a split ring 1 A helicalspring 8D surrounds the core members 13 and 15 and is held at s oppositeends to the ilanges 12 and 16, respectwst of the spring 80, revolution.

The spool-end flange 69 has an axially outstanding brake band or ratchetannulus 84 on its outer side, thereby rendering the spool-end at thatside of counter-sunkor depressed character; the annulus 84 having aradially-inwardly-opening groove 85of axial V-section providingclutching, wedging, braking or ratcheting surfaces. By moving the latchmember 58, against the action of the spring 63, to move the arm 60 fromposition opposite the adjacent end of the axle 50, and by pressingagainst the rounded end 54 of the axle, the bobbin assembly may beremoved from the standard as a unit, in which the core parts, includingthe sleeve 13 and 15 and parts thereon, are locked axially to the outerspool portions. By disconnectlng a spring 98, a clutch or brakethe brakeshoe entirely out of the groove 85, so that the outer and core bobbinparts may be separated.

As better seen in Figs. 7 and 8, the sleeve 15 has three substantiallyradial arms 81, 88 and 89 disposed in closely-related parallel planerelation tol the adjacent end of the bobbin; the arm 81 pivotallysupporting, as by a pin 90, a brake-shoe arm or lever 92 having, at oneend, or on a short arm thereof, a clutch member, brake shoe or detentportion 93 of substantially V-section conforming to the groove 85, and,at its other end, or on its longer arm, a hook 95 and a stop portion 96.A tension spring 98, connected between the hook 95 on the lever 92 and asimilar hook 99 on the arm 88 biases the brake shoe 93 toward the groove85 for intermittent braking coaction therewith.

The structure including .the sleeve 15 and the arms 81, 88 and 89 isbiased counterclockwise, in the direction of an arrow A, as viewed inFig. 8, by the spring inside the bobbin, such that it tends to assumethe position wherein the arm thereof engages a cooperating stop or lug|00 on the standard arm 23. In this position, the spring 98, by the longleverage of the arm 92, Vengages the brake shoe 93 to the sides of theV-groove to effectively grip the latter so that, when tension is exertedon the strand 66, in feedaction of the spring 80. At approximately theend of a revolution, during which the spring 89 becomes fully wound, thestop 96 engages the a brake to reduce stop |00, as seen :inFi-g. T;whereupon arms 89 ,and 92 move relative to each other-against vtheaction of the spring 98 to release the brake shoe 93 from the brake 85,toallow the spool to` rotate freely on the flanges 13 and 15, and tothereby, permit more than the single turn ofthestrand 66, thus unwound,to feed oi the bobbin. The spring 80, being thus momentarily relieved ofthe strand tension, tends to return the inner orbrake-shoe-carryingparts to starting position free from the outer spoolparts, whereupon, after a certain returning, ,movement the spring 98again acts to engage the brake, shoe to the brake. In this way, andvby'intermittent repetition of this action, thestrand is continuously fedfrom the outer spool, which also continuously rotates, but does so by somanyand so rapidly repeated connections to, and disconnections from, thebobbin core and'springparts, as toobtain. nearly the effect` o-f havingthe strand vcontinuously spring tensioned. )This is, in a `fine degree,different from a pawl and ratchet device, vasin the modified form of'the invention shown in Figs. 10, l1 andA 12, in that in the latter, thestrand is released from and reengaged Ato the spring in .uniform steps,each form having its uses Viand applications, but the wedge-brake formabove described operating instantaneously at any part in the bobbinmovement irrespective of ratchet steps. l y

When the strand breaks, orrelaxes its tension to suiiicient degree, theparts are returned to the position of Fig. 8 wherein the arm 89 notAonly engages the stop but also vmoves the lever 32 downwardly, spring31,'to cause one of the wings 34 to actuate the stop-motion lever. ,i 'f

, It will readily be appreciated that the members .05 `and ,93v effectand operate asa clutch mechanism for intermittently connecting anddisconnecting the vtensioning spring 80 to and from the bobbin, inasmuchas this action may take place at` anyr instant and does not require thatthe associated elements be moved to predetermined positions ,in order toeffect proper operation thereof. VThe clutch elements 85 and 93 functionto anchor the Ybobbin tothe tensioning spring 80 during rotation of thebobbin from the position sho-wn in Fig. 8 until thestop portion 96 abutsthe stop |00', whereupon the clutch member 93 is disengaged from theannular clutching surface 85 and free unwinding rota.- tion of thebobbin is permitted. Immediately subsequent to the disengaging of theclutch member 93 from the annular ange 85, the -aevtion of the spring 80rotates the sleeve 'l5 in the direction of the arrow shown in Fig.8,*thus the member 96 is moved clearo the stop |00,-where- Yupon theclutch element 93 is moved into clutching `engagement with the annularvclutchingsurface 85 throughttheaaction` ofv the spring 98. Thus theentire device serves as a tensioning structure for the. yarn fedtherefrom, and includes elements which successively operate:` as

the rotative speed of the bobbin; as a clutch topengage `the corestructure to the bobbin;` and as a detent to anchor the core structureto the bobbin to prevent relativemovement therebetween; t, In themodification of the invention shown in Figs. 10, 11 and 12, aside fromminor differences of size and form, the parts are similar to those abovedescribed, except that, lin the place of the brake annulus having theV--groove 85, there is provided a ratchet wheel |02 having `internal||0, similar to the stop the -sleeve end4|08, like the arm 89, is foren,-

against the action of Aits teeth,:..and;..in'theiplaces of the'brake-shoe arm 'on which channeled sides |08 of the pawl |03 ,slide in aslot between' the edges |01; the pawl 'also-havin'g'a portion |09 forengagement, at

the end of its clockwise movement, with a stop |00. A portion ||2 ongagement, at-the end of its counterclockwise movement, with the stopmotion lever 32 and the stop |I0. A spring H4, between the pawl ,|031and the sleeve end |06, corresponds to the spring,98.gThe ratchetwheel|02 is secured to the bobbin cylinder,-as by screws H5, and has `aflange ||1 corresponding to the flange 69. Further,`y the axle extendsthrough the bobbin in theopposite direction, as indicated by theposition of the small shank` portion 53 and the rounded end -54-adjacent to the ratchet.

This'device operates similarly to the form` rst described, except thatthe bobbin is released by, vand moves relative tothe brake or ratchet inuniform steps.
